The world’s first electronic instrument, the theremin, was invented in the Soviet Union in 1928, and in the ensuing decades, castoffs from the country’s defense and space industries were repurposed to power an avant-garde music scene that has only recently come to light. Including interviews with Leon Theremin and his contemporary disciples, this quirky new documentary shows how creativity bloomed even in the harsh climate of the U.S.S.R. “A heartfelt tribute to the men…who through their deviousness, ornery resourcefulness and enterprising ingenuity crafted machines which made sounds never heard before or since.” – Neil Young, The Hollywood Reporter.
